図１乃至図７に示す本発明を実施するための第１の形態において、１は作業現場で組み立てて使用可能な組立式クレーンである。 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.
In the first embodiment for carrying out the present invention shown in FIGS. 1 to 7, reference numeral 1 denotes an assembly type crane that can be assembled and used at a work site.

なお、前後方向とは図１における左右方向（前：右、後：左）、上下方向とは図１における上下方向、左右方向とは図３における左右方向をいう。   Note that the front-rear direction is the left-right direction (front: right, rear: left) in FIG. 1, the up-down direction is the up-down direction in FIG. 1, and the left-right direction is the left-right direction in FIG.

この組立式クレーン１は、図１乃至図３に示すように自走可能な走行装置２を備える基台３と、該基台３に前後方向にスライド移動可能に取り付けられ、ウインチ４を備える操作台５と、該操作台５に設けられたブーム取付部６と、該ブーム取付部６に後端部が回転可能（起伏可能）に取り付けられたブーム７と、前記操作台５に設けられ前記ブーム７を作動させる起伏シリンダー８と、前記操作台５を前後方向にスライド移動させる操作台移動手段９とで構成されている。   As shown in FIGS. 1 to 3, the assembly type crane 1 includes a base 3 having a traveling device 2 capable of self-propelling, and an operation having a winch 4 attached to the base 3 so as to be slidable in the front-rear direction. A base 5, a boom attachment portion 6 provided on the operation base 5, a boom 7 whose rear end portion is rotatably attached (can be raised and lowered) to the boom attachment portion 6, and provided on the operation base 5. The hoisting cylinder 8 that operates the boom 7 and the operation table moving means 9 that slides the operation table 5 in the front-rear direction are configured.

基台３は、本実施形態においては、平面視略長方形のフレーム状で、Ｈ鋼で構成されており、Ｈ鋼の凹所が側面に位置するように構成されている。
基台３の下部には、走行装置２として無限軌道２を備えており、基台３は本実施形態において無限軌道２よりも後方に長い寸法に形成されている。 In the present embodiment, the base 3 has a substantially rectangular frame shape in plan view and is made of H steel, and the recess of the H steel is located on the side surface.
An endless track 2 is provided as a traveling device 2 below the base 3, and the base 3 is formed in a longer dimension behind the endless track 2 in this embodiment.

操作台５は、前記基台３に取り付けられる取付部材１０と、該取付部材１０の上部に回転台１１を介して設けられた操作台本体１２とで構成されている。取付部材１０の底面には前記基台３の内側側面に当接するガイド部材１３が設けられている。このガイド部材１３は、取付部材１０の前後方向に延在するように設けられた一対の板状の部材で、取付部材１０から下方へ突出し、その下端部付近は内側に折れ曲がるような傾斜面１４となっている。   The operation table 5 includes an attachment member 10 attached to the base 3 and an operation table body 12 provided on the upper part of the attachment member 10 via a rotary table 11. A guide member 13 that contacts the inner side surface of the base 3 is provided on the bottom surface of the mounting member 10. The guide member 13 is a pair of plate-like members provided so as to extend in the front-rear direction of the attachment member 10, and protrudes downward from the attachment member 10, and an inclined surface 14 that is bent inward near its lower end. It has become.

このような傾斜面１４を備えているため、クレーンやヘリコプターを使用して上方から操作台５を基台３に取付ける際に、ガイドとなりスムーズに取付けることができる。また、ガイド部材１３は、基台３の内側面に略当接するので、左右方向の位置決めもすることができる。   Since such an inclined surface 14 is provided, when the operation console 5 is attached to the base 3 from above using a crane or a helicopter, it can serve as a guide and can be attached smoothly. Moreover, since the guide member 13 substantially contacts the inner surface of the base 3, it can be positioned in the left-right direction.

操作台本体１２の後部には、前記走行装置２を駆動させるエンジン１５が設けられている。
また、操作台本体１２の後部には、ブーム７の後端部を取付けるブーム取付部６と、ブームを支持する一方のブーム支持部材１６が設けられている。この一方のブーム支持部材１６は、本実施形態ではブーム取付部６よりも前方に設けられている。他方のブーム支持部材１７は基台３の前方側に設けられており、ブーム７を取付ける際に、この前後のブーム支持部材１６、１７にブーム７を仮置きし、取付作業を行う。
これらのブーム支持部材１６、１７は、本実施形態では、略逆コ字状に形成されており、その上端部付近には、上方に向かって略逆ハの字状に拡開するガイド部２２が形成されている。 An engine 15 that drives the traveling device 2 is provided at the rear of the operation console main body 12.
Further, a boom mounting portion 6 for attaching the rear end portion of the boom 7 and one boom support member 16 for supporting the boom are provided at the rear portion of the operation console main body 12. This one boom support member 16 is provided in front of the boom mounting portion 6 in this embodiment. The other boom support member 17 is provided on the front side of the base 3, and when the boom 7 is attached, the boom 7 is temporarily placed on the front and rear boom support members 16, 17 to perform attachment work.
In the present embodiment, these boom support members 16 and 17 are formed in a substantially inverted U shape, and in the vicinity of the upper end portion thereof, a guide portion 22 that expands in a substantially inverted C shape upward. Is formed.

ブーム７は、一般的に用いられるブームが想定される。例えば、その後端部が前記ブーム取付部６に回動可能（起伏可能）な状態で取り付けられ、その中央部付近には、ブーム７を支持するとともに起伏させる起伏シリンダー８の作動杆８ａが取り付けられている。また、ブーム７の先端部には滑車１８が設けられている。   The boom 7 is assumed to be a commonly used boom. For example, the rear end portion is attached to the boom attachment portion 6 so as to be rotatable (can be raised and lowered), and an operating rod 8a of the raising and lowering cylinder 8 that supports and raises the boom 7 is attached near the center portion thereof. ing. A pulley 18 is provided at the tip of the boom 7.

このブーム７の滑車１８には前記ウインチ４のワイヤー１９を通過させ、ワイヤー１９の先端部には被吊り上げ物を吊り上げるフック２０が設けられる。
操作台移動手段９は、本実施形態では２本の油圧シリンダー９で構成されており、この油圧シリンダー９は、その基端部が基台３の前方側の端部に固定され、作動杆９ａの先端部が操作台５に固定されている。図７に示すように、この油圧シリンダー９を伸縮することにより、操作台５が前後方向に移動する。 A wire 19 of the winch 4 is passed through the pulley 18 of the boom 7, and a hook 20 for lifting an object to be lifted is provided at the tip of the wire 19.
The operation table moving means 9 is constituted by two hydraulic cylinders 9 in this embodiment, and the hydraulic cylinder 9 has its base end fixed to the front end of the base 3 and an operating rod 9a. Is fixed to the operation table 5. As shown in FIG. 7, by extending and contracting the hydraulic cylinder 9, the operation console 5 moves in the front-rear direction.

重い物を吊り上げる場合には、油圧シリンダー９の作動杆９ａを伸長させ、操作台５を後方へ移動させることにより、組立式クレーン１の重心が後方へ移動する。操作台５を基台３の後端部付近まで移動させた場合には、組立式クレーン１の重量と略同一重量の対象物を吊り上げることができる。   When a heavy object is lifted, the center of gravity of the assembly type crane 1 is moved backward by extending the operating rod 9a of the hydraulic cylinder 9 and moving the operation table 5 backward. When the operation table 5 is moved to the vicinity of the rear end portion of the base 3, an object having substantially the same weight as the weight of the assembly type crane 1 can be lifted.

本願発明の組立式クレーン１を組み立てる場合には、図４に示すように、作業現場に基台３を配置し、この基台３をクレーンやヘリコプターを使用して操作台５を載置する。その後、クレーンやヘリコプターを使用してブーム支持部材１６、１７にブーム７を仮置きする。   When assembling the assembling crane 1 of the present invention, as shown in FIG. 4, a base 3 is arranged at a work site, and the operating base 5 is placed on the base 3 using a crane or a helicopter. Thereafter, the boom 7 is temporarily placed on the boom support members 16 and 17 using a crane or a helicopter.

操作台５はガイド部材１３によってスムーズに基台３に載置されるため、ヘリコプターを使用する場合でも短時間で載置できる。また、ブーム７もブーム支持部材１６、１７に仮置きするだけなので、短時間で仮置きすることができる。   Since the operation table 5 is smoothly placed on the base 3 by the guide member 13, it can be placed in a short time even when a helicopter is used. Further, since the boom 7 is only temporarily placed on the boom support members 16 and 17, it can be temporarily placed in a short time.

このように基台３に操作台５を載置したら、Ｈ鋼の凹所に係合する左右一対の係合部材２１を操作台５（取付部材１０）の左右端部に固定し、基台３に操作台５を取付ける。本実施形態では係合部材２１は、金属製でアングル状の板状部材であり、ボルト等によって取付部材１０の左右側面に着脱可能に固定される。   When the operation table 5 is placed on the base 3 in this way, a pair of left and right engaging members 21 that engage with the recesses of the H steel are fixed to the left and right ends of the operation table 5 (attachment member 10). Attach the operation console 5 to 3. In this embodiment, the engagement member 21 is a metal-made angle-shaped plate-like member, and is detachably fixed to the left and right side surfaces of the attachment member 10 with bolts or the like.

このような係合部材２１を用いて基台３に操作台５を取付けることにより、Ｈ鋼の前後方向に延在する凹所がガイドレールのようになり、操作台５は前後方向に移動可能な状態で取り付けられる。   By attaching the operation table 5 to the base 3 using such an engaging member 21, the recess extending in the front-rear direction of the H steel becomes like a guide rail, and the operation table 5 is movable in the front-rear direction. It is attached in a state.

また、基台３に操作台５を載置してしまえば重機等を用いずに少人数で組み立てることができるので、重機やヘリコプターの稼働時間等を少なくすることができる。
ブーム７を組み立てる場合には、図５に示すように、まず、前後のブーム支持部材１６、１７にブーム７を仮置きするが、この時ブーム７の後端部がブーム取付部６よりも前方に位置するように仮置きする。 Further, if the operation table 5 is placed on the base 3, it can be assembled by a small number of people without using heavy machinery or the like, so that the operating time of heavy machinery or helicopters can be reduced.
When assembling the boom 7, as shown in FIG. 5, first, the boom 7 is temporarily placed on the front and rear boom support members 16, 17. At this time, the rear end portion of the boom 7 is forward of the boom mounting portion 6. Temporary placement so that it is located at.

仮置きしたら起伏シリンダー８の作動杆８ａを伸長させて、起伏シリンダー８の作動杆８ａの先端部をブーム７に固定し、図６に示すように、起伏シリンダー８の作動杆８ａを縮める。そうするとブーム７はブーム支持部材１６、１７に支持されたまま後方へスライド移動し、ブーム７の後端部がブーム取付部６の位置まで移動したら作動杆８ａの縮小を止める。このように組み立てることにより、他の重機を使用しなくても少人数でアーム７を組み立てることができる。   When temporarily placed, the operating rod 8a of the hoisting cylinder 8 is extended, the tip of the operating rod 8a of the hoisting cylinder 8 is fixed to the boom 7, and the operating rod 8a of the hoisting cylinder 8 is contracted as shown in FIG. Then, the boom 7 slides backward while being supported by the boom support members 16 and 17, and when the rear end portion of the boom 7 moves to the position of the boom mounting portion 6, the reduction of the operating rod 8a is stopped. By assembling in this way, the arm 7 can be assembled with a small number of people without using other heavy machinery.

[発明を実施するための異なる形態]
次に、図８乃至図１３に示す本発明を実施するための異なる形態につき説明する。なお、これらの本発明を実施するための異なる形態の説明に当って、前記本発明を実施するための第１の形態と同一構成部分には同一符号を付して重複する説明を省略する。
図８乃至図１０に示す本発明を実施するための第２の形態において、前記本発明を実施するための第１の形態と主に異なる点は、板状の基台３Ａを用い、この基台３Ａに前後方向に移動可能に操作台５を係合部材２１Ａを用いて係合状態で取り付けるとともに、ガイド部を有しない一対のブーム支持部材１６Ａ、１７Ａとした点で、このような組立式クレーン１Ａにしても、前記本発明を実施するための第１の形態の削孔作業車と同様な作用効果が得られる。本実施形態では、基台３Ａの底面にアングル状の係合部材２１Ａが係合し、操作台５が前後方向に移動可能に取り付けられている。 [Different forms for carrying out the invention]
Next, different modes for carrying out the present invention shown in FIGS. 8 to 13 will be described. In the description of the different embodiments for carrying out the present invention, the same components as those in the first embodiment for carrying out the present invention are denoted by the same reference numerals, and redundant description is omitted.
The second embodiment for carrying out the present invention shown in FIGS. 8 to 10 is mainly different from the first embodiment for carrying out the present invention in that a plate-like base 3A is used. The operation table 5 is attached to the table 3A in the engaged state using the engagement member 21A so as to be movable in the front-rear direction, and a pair of boom support members 16A and 17A having no guide portion are used. Even with the crane 1A, the same effect as the drilling work vehicle of the first embodiment for carrying out the present invention can be obtained. In the present embodiment, the angle-shaped engaging member 21A is engaged with the bottom surface of the base 3A, and the operation table 5 is attached so as to be movable in the front-rear direction.

図１１乃至図１３に示す本発明を実施するための第３の形態において、前記本発明を実施するための第１の形態と主に異なる点は、角材を用いてフレーム状に形成した基台３Ｂを用い、この基台３Ｂに前後方向に移動可能に操作台５を係合部材２１Ａを用いて係合状態で取り付けると共に、操作台５の前方側の端部にブーム支持部材取付部２３を設け、このブーム支持部材取付部２３に他方のブーム支持部材１７を固定した点で、このような組立式クレーン１Ｂにしても、前記本発明を実施するための第１の形態の削孔作業車と同様な作用効果が得られる。   The third embodiment for carrying out the present invention shown in FIGS. 11 to 13 is mainly different from the first embodiment for carrying out the present invention in that the base is formed in a frame shape using square bars. 3B is used, and the operating table 5 is attached to the base 3B in an engaged state using an engaging member 21A so as to be movable in the front-rear direction, and a boom support member mounting portion 23 is attached to the front end of the operating table 5. The drilling work vehicle according to the first embodiment for carrying out the present invention is provided even in such an assembly-type crane 1B in that the other boom support member 17 is fixed to the boom support member mounting portion 23. The same effect can be obtained.

本実施形態のブーム支持部材取付部２３は、操作台５の操作台本体１２の前方側端部に枢支ピン２４によって左右方向に回動可能に取り付けられており、ブーム７を組み立てる際には、一対のブーム支持部材１６、１７が前後方向に直線状に並ぶように位置させ、ブーム７を取り付けた後は、ブーム支持部材取付部２３を回転させて、ブーム７の動きを邪魔しない位置に位置させることができる。このように枢支ピン２４を介してブーム支持部材取付部２３を設けてもよいし、操作台５の操作台本体１２に一体的にブーム支持部材取付部２３を備えて他方のブーム支持部材１７を固定してもよい。   The boom support member mounting portion 23 of the present embodiment is attached to the front side end portion of the operation table body 12 of the operation table 5 so as to be turnable in the left-right direction by the pivot pin 24, and when assembling the boom 7. The boom support members 16 and 17 are positioned so as to be linearly arranged in the front-rear direction, and after the boom 7 is mounted, the boom support member mounting portion 23 is rotated so that the movement of the boom 7 is not disturbed. Can be positioned. In this way, the boom support member mounting portion 23 may be provided via the pivot pin 24, or the boom support member mounting portion 23 is provided integrally with the operation table main body 12 of the operation table 5, and the other boom support member 17 is provided. May be fixed.

なお、本発明の実施形態においては、操作台移動手段として油圧シリンダーを用いるものを説明したが、例えば基台の内側側面にラックを備え、操作台の側面にこのラックと噛み合うピニオンを備えて操作台移動手段としてもよい。   In the embodiment of the present invention, a hydraulic cylinder is used as the operating table moving means. However, for example, a rack is provided on the inner side surface of the base and a pinion meshing with the rack is provided on the side surface of the operating table. It may be a table moving means.

また、ブームについても伸縮できるブームを用いてもよく、一対のブーム支持部材を備えない組立式クレーンとしてもよい。   Moreover, the boom which can be expanded-contracted also about a boom may be used, and it is good also as an assembly-type crane which is not provided with a pair of boom support member.
